LGTM if CI passes. We really need to change this test to use a mock.

I am going to cherry-pick this change to all active branches (3.8, 3.9, 4.0)

@divijvaidya -- Seems this cherry-pick did break 3.9 and 3.8 branches.

Pushed a fix into both branches already. So no action needed.

List.of is not supported in Java8... Please compile locally (ideally even run related unit/integration tests) before pushing cherry-picks to older branches.

Just a reminder, especially as we dropped Java8, we need to switch Java version when switching branches, so compiling cherry-pick locally is even more important now than it was before.

[divijvaidya]

I understand. Sorry about that @mjsax.

I'd say running ./gradlew check -x test for clean cherry-picks is usually enough. It will do the right thing when it comes to Java support automatically.
